MACHINE FOR INFOLDING TAB-BLANKS.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed July 7,1902. Serial No. 114,558.

To all whom it may concern.-

Be it known that we, JAMES K. P. PINE and GARRY J. DORMANDY, residents of the city of Troy, county of Rensselaer, and State of New York, have jointly invented new and useful Improvements in Machines for Infolding Tab-Blanks, of which the following is a specification.

Our invention relates, broadly, to foldingmachines, and specifically to mechanism adapted to infold or inturn the edges of blanks such as used in the manufacture of apparel articles, particularly to that class of blanks from which are formed the tabs of bosom-shirts, shirtwaists, and other garments, it being a purpose of our invention to produce the infolds upon the edges of the blank with rapidity and to give greater uni formity to the folded tabs.

Accompanying this specification to form a part of it there are five plates of drawings containing nine figures illustrating one form of mechanism embodying our invention, with the same designation of parts by letter reference used in all of them.

Of the illustrations, Figure 1 is a top view of a machine containing our invention with the infolders shown as resting upon the bed and with the templet and templet-operating parts removed. Fig. 2 is a front end elevation of the machine shown in Fig. 1. Fig. 3 is a cross-section taken on the line as at of Fig. 1. Fig. 4 is a side elevation of the machine shown in Fig. 1 with the part F and the templet carried by it shown in lower position by full lines and as partly raised by dotted lines. Fig. 5 is a vertical longitudinal section taken on the line x m of Fig. 2.. Fig. 6 shows a detached view of the infolders of Fig. 1, and Fig. 7 a bottom view of the bar A on which the infolders are mounted. Fig. 8 is a detail top view of the bell-crank lever It, slide-plate d connected therewith, and the templet T of Figs. 2 and 4. Fig. 9 is a view of the under side of the plate on which the templet is mounted, showing also the templet. Fig. 10 is aplan view of the blank before being infolded, and Fig. 11 is a plan view of one of the blanks after having been infolded.

The several parts of the apparatus thus illustrated are designated by letter reference,

and the function of the parts is described as follows:

The letter T designates a convenient form of table or platform upon which to mount a machine.

B designates the bed of a machine embodying our invention, whereon at the front blanks may be placed to be infolded.

II designates a chamber which may be formed in the bed B beneath that part of the latter upon which the blanks to be infolded are supported, and the letters 10 p designate two pipes whereby steam may be caused to circulate in said chamber to heat that portion of the bed whereon the blanks are infolded to assist in firmly fixing the infolds formed on the blanks.

A designates a T-form bar adapted to be moved forwardly and backwardly as by means of slides a formed for convenience 1n the bed B, as illustrated at Figs. 1 and 5.

Letters I I designate two infolders, shown as plates, and which are cut away interiorly to inclose an area m occupied by the bar A. These infolder-plates I I are made to lap past each other at 11. and where thus lapping past each other they are pivoted to each other by being together pivoted to the under side of the bar A at P The specific form of machine being described is adapted for operating upon blanks whose folded edges will be U-shapcd. For this purpose the infolders are shaped to afford curved edges e e and edges 6 e to produce when comibned a U-form area U, which the infolders as thus cut away inclose. Each infolder has formed at its rear end a slot S, arranged to have a cam action (this being a convenient infolder oscillating means) with pins D, fixed at either side of the bed B, and provided, when desired, with rollers. As thus arranged, when the bar A and connected infolder-plates I are together moved frontwardly the infolding edges of the plates will be moved both frontwardly and at the same time by the cam action described moved inwardly, thus causing the side infolding edges 6 e of the plates I I to be moved toward each other by reason of the oscillation of the infolders.

L designates a bell-crank lever, comprising an operating-handle 7L2 and an arm 1 that is be next lowered to move frontwardlv the bar caused to rise and is pivoted to the side of the bed at Z and its upper end P extended horizontally to engage with and bear upon the rear vertical ace of the left-hand extension a of the bar A, as illustrated in Figs. 1 and 4.

The letter S designates a spring, connected at the rear with a vertical standard J and at the front with the bar A to pull the latter rearwardly and resist the operation of the handle if when the latter is ressed downwardly to move the bar A an connected infolder-plates I I frontwardly.

We will now describe a preferable form of templet and operating mechanism therefor.

F designates an oscillating member, which at its rear end is overbalanced by a weight W, depending from the rear extension f of the member F. A yoke Y carries the member F and is pivotedly supported by its two arms y 1 to the bed at y y R designates another bell-crank lever, which at r is pivoted to extensions r of the member F, and lever R is provided with an operating-handle r and having its downwardly-extended arm r arranged between two posts (Z d and its slot 1* engaging a pin extending from'post to post, as illustrated at Figs. 2, 4, and 5. These posts each connect at their lower end to a slide-plate (i arranged in a guide or slide (i and depending from said slide-plate there is arranged a templet-stock, secured to which is the templet-plate or templet proper, T as shown at Figs. -2, 4, and 5. As thus constructed, by operating the lever R by depressing the outer end of its handle the templet T is moved inwardly or backwardly in proper position to rest upon a blank placed on the bed. When the member F is pressed downwardly on its pivotal connection against the action of the weight W, the templet T being in the rearward osition of Fig. 4, the latter will in operation e brought to bear directly upon the blanks upon the bed and within edge portions of the blanks. With the parts thus placed the lever L may A and connected infolder-plates I I. The forward movement of the infolder edges 6 e efiects the infolding of the corresponding part of the tab-blank, and the swinging motion of the edge portions 6 e of the infolderlates carries the remaining edges of the blanks to be infolded over other edge portions of the tem let to form infolds. After the infolds thus formed have been 7 ressed in any well-known manner, or as will e hereinafter particularly described, the pressure upon t e ivoted lever L is removed and the barA an infolders I Iare drawn rearwardly by the action of the spring S and the member F by the action of the counterpoise is put in suitable position for a new operation.

We will now describe a convenient pressing mechanism.

G designates a presser-head or presser arranged to bear downwardly upon the bar A by means of a connecting-rod M, that extends through openings 0 and O in the bar A, and the table T, res ectively, toasuitable treadle device T the atter provided with suitable spring S to restore the treadle and presser to normal osition after a pressin operation. Obviously on lowering the tread e following an infolding operation and preferably after the templet is withdrawn from the folds, but before the blanks are disturbed and before the infolders are withdrawn, the presser G through the bar A will effect a squeezing of the folds of the blanks between the infolders and the heated bed to fix the folds with a sharp crease. i i

We do not limit our invention as herein set forth and described to the infolding of the particular form of blanks illustrated, nor to any specific details where the same may be changed without departing from the spirit of our invention.

Having thus described a machine embodying our invention, what we claim, and desire to secure by Letters Patent, is
